Find Out The Least Count Of A Vernier Caliper When Its Main Scale Graduation Is 49 Mm And The Vernier Scale Is Divided In To 50 Equal Parts?

Answer»
  • Value of 1 MAIN SCALE division = 1 mm
  • Value of 50 vernier scale divisions = 49 mm
  • Value of 1 vernier scale division = 49 x 50 mm or 0.98 mm
  • LEAST COUNT = 1 M.S.D – 1 V.S.D = 1 – 0.98 = 0.02 mm
